Michael,
You probably tested the system's integrity and functionality, and all appeared
fine. What you probably did not generate was the equivalent of a realistic
production load (POP + IMAP + LMTP).
We found ourselves in a similar situation two years ago (with eternal thanks
to Simon Matter who helped us *enormously* with a suggestion written on this
mailing list).

Eric Luyten (now running 2.3 for +70k users with 50M messages, wondering
what server and I/O load we will observe when upgrading to 2.4)
